The Seattle Mariners are showcasing one of the strongest minor league systems in Major League Baseball, with eight players featured on Baseball America's top 100 prospects list. This depth could translate into significant contributions to the major league roster as early as 2025, with players like Cole Young and Logan Evans expected to make their mark.

Baseball America's recent projections for the Mariners' 2028 lineup indicate a dramatic transformation, retaining only catcher Cal Raleigh and star outfielder Julio Rodriguez. The starting pitching rotation, however, is expected to remain largely intact, with Logan Evans potentially stepping in for veteran Luis Castillo.
